    English translation of PCT/CN2012/083555 VALUABLE FILE IDENTIFICATION DEVICE [0001] The present application claims the benefit of priority to Chinese Patent Application No. 201210062147.4 titled "VALUABLE DOCUMENT IDENTIFICATION DEVICE", filed 5 with the Chinese State Intellectual Property Office on March 9, 2012, the entire disclosure of which is incorporated herein by reference. FIELD OF THE INVENTION [0002] The present application relates to information collecting technology of a sheet-like 10 medium, and particularly to a solution which can effectively solve the problems that there is interference between various information collecting elements and the medium is tilted or deformed in the collecting and conveying process. BACKGROUND OF THE INVENTION 15 [0003] An identification device for identifying characteristics of financial notes to be processed is required to be mounted on an equipment for processing the financial notes. For example, financial equipments, for example the cash automatic teller machine (ATM), the banknote sorter and the cash counter, are all provided with the banknote identification device for identifying information of the banknote, for example the sorts, the face value, the facing 20 orientation and the authenticity. Specific identifiable anti-fake labels are added on the banknote during the design and print process, such that various sensors are arranged in the above banknote identification device to detect and obtain relevant information of the anti-fake labels, for example an optical image sensor is provided to obtain a surface image or a projection image of the banknote by irradiating the banknote with lights of different wave 25 lengths, and a magnetic sensor is provided to detect a magnetic printing ink and a metal safety wire which are added on the banknote during the print process. In order to precisely identify the banknote, generally multiple optical image sensors and magnetic sensors are provided in one identifying and detecting device. [0004] A banknote identification device is disclosed in Chinese Patent No. CN 1818978A, 30 in which multiple magnetic sensors and multiple optical image sensors are alternatively provided. Referring to Figure 1, multiple rollers 106 to IIl are provided on a conveying - i - English translation of PCT/CN2012/083555 passage 10 of the banknote identification device 1, and two optical sensors 101, 103 and two magnetic sensors 102, 104 are alternatively provided at two sides of the conveying passage 10. When the banknote enters the banknote identification device 1 in a direction A, the optical sensor 101 is used to eliminate a deviation of the above sensors provided downstream the 5 optical sensor 101. The optical sensor 103 is used to detect characteristics of the banknote under specific wave lengths. The magnetic sensor 102 is used to detect a magneto-impedance characteristic of the banknote, and the magnetic sensor 104 is used to detect a magnetic resistance characteristic of the banknote. Various information of the magnetic resistance is identified when the banknote passes through the above sensors in the conveying passage 10. 10 [00051 Various sensors are used in the banknote identification device, which may cause mutual interference between adjacent sensors, thus may cause interference for information collection and the system being unstable. {0006] Further, during the note conveying process, the note needs to be conveyed at a high speed in the financial equipment. When the note passes through the above identification 15 device, in which the note is clamped and conveyed by the linear conveying passage cooperating with conveying rollers, at a high speed, it is hard to avoid the note being tilted. Since the note is tilted in the identification device, the information acquired by various identification sensors has a worse regularity, which may cause a huge workload for processing the identification information. 20 SUMMARY OF THE INVENTION [0007] One object of the present application is to provide a valuable document identification device which can effectively solve the problems that there is interference between various information collecting elements and the medium is tilted or deformed during 25 the collecting and conveying process. [0008] The valuable document identification device includes: [0009] a hollow transparent rotating cylinder assembled with mounting side walls via a hollow bearing; 100101 an annular clamping belt supported by at least two tension rollers and abutted 30 against an outer surface of the transparent rotating cylinder, wherein a clamping and -2- English translation of PCT/CN2012/083555 conveying passage of the valuable document is formed between an outer surface of the annular clamping belt and the outer surface of the transparent rotating cylinder, and has a length greater than a length of the valuable document in a conveying direction, and two ends, formed by the two tension rollers, of the annular belt functions as an inlet and an outlet of the 5 clamping and conveying passage for the valuable document respectively; [00111 at least one information collecting device, an information collecting element of which is close to an inner surface of the transparent rotating cylinder and faces at least a portion of the outer surface of the annular clamping belt, and the information collecting element is unmovable relative to the mounting side walls; and 10 [00121 a power driving device, which drives the transparent rotating cylinder and the annular clamping belt to move synchronously in opposite directions. [0013] Preferably, the annular clamping belt is a nontransparent belt. [00141 Preferably, a driven wheel is provided at the inlet of the clamping and conveying passage at a position corresponding to the tension roller. 15 [0015] Preferably, an inlet end and an outlet end of the clamping and conveying passage are both provided with a guiding sheet for guiding the valuable document to smoothly enter and leave the clamping and conveying passage. [0016] Preferably, a driven wheel is provided at the outlet of the clamping and conveying passage. 20 [0017] Preferably, the valuable document identification device further includes a depth collecting device mounted on a conveying path through which the valuable document enters or leaves the clamping and conveying passage. [0018] Preferably, the valuable document identification device further includes a magnetic signal collecting device mounted on a conveying path through which the valuable document 25 enters or leaves the clamping and conveying passage. [00191 Preferably, a mounting position relationship between the information collecting element of the information collecting device and the transparent rotating cylinder is required to meet the following condition: [00201 FOV = 8 xWN 7r x Ha -3- English translation of PCT/CN2012/083555 [0021] Wherein, "FOV" is a field angle of the information collecting element, "WN" is a width of the valuable document collected within the field angle, "Ha" is a distance between the valuable document and an apex of the field angle, and "WN" is equal to the minimum note-like medium width "WNmin" collected by the collecting device and calculated according 5 to the requirement of image collection resolution. [0022] Preferably, in order to accomplish the information collection of two sides of the valuable document by only conveying the valuable document once, the valuable document identification device includes two sets of the hollow transparent rotating cylinder, the annular clamping belt, the information collecting device and the power driving device, which are 10 symmetrically arranged, wherein the valuable document enters an inlet of another clamping and conveying passage from an outlet of one clamping and conveying passage. {0023] Preferably, the valuable document identification device further includes a casing for receiving all components, wherein the mounting side walls are a part of the casing, and the casing is provided with openings, at positions corresponding to the inlet and the outlet of the 15 clamping and conveying passage respectively, for the valuable document to enter and leave. [0024] Compared with the prior art, the valuable document identification device has the following advantages. [0025J 1. When clamping and conveying the valuable document, the valuable document conveying passage, formed by the transparent rotating cylinder and the annular clamping belt, 20 provides a continuous static friction force for the valuable document, such that the conveying manner in which the conveying passage and the valuable document are relatively static may solve the problem that the valuable document is tilted or deformed in collecting process, thereby improving the identification effect of the note-like medium. t00261 2. The valuable document conveying passage, formed by the transparent rotating 25 cylinder and the annular clamping belt, is of an arc shape, such that when multiple information collecting elements arranged therein are working simultaneously, the mutual interference therebetween is avoided. For example, optical sensors for collecting the image information of the valuable document can not work simultaneously when being arranged very close to each other. 30 -4- English translation of PCT/CN2012/083555 BRIEF DESCRIPTION OF THE DRAWINGS [0027] The accompanying drawings are provided to help further understanding of the present application and constitute a part of this specification.

DETAILED DESCRIPTION OF THE INVENTION [0038] In order to further describe the present application, one preferred embodiment of the present application is illustrated below in conjunction with drawings. -5- English translation of PCT/CN2012/083555 [0039] Referring to Figure 2, the present application provides a valuable document identification device, which may realize the collection of information on two sides of a valuable document by conveying the valuable document once. The valuable document identification device includes a casing 1; two hollow transparent rotating cylinders 21, which 5 are arranged symmetrically in the casing I and assembled with two side walls of the casing I correspondingly via hollow bearings (not shown in Figure 2, reference may be made to Figure 5); and two nontransparent annular clamping belts 41, each of which is supported by 12 tension rollers 301 to 312 and abut against an outer surface of one corresponding transparent rotating cylinder 21, wherein a clamping and conveying passage of the valuable document is 10 formed between an outer surface of each of the annular clamping belts 41 and the outer surface of the corresponding transparent rotating cylinder 21, and the clamping and conveying passage has a length greater than a length of the valuable document in a conveying direction. Two ends, formed by the tension rollers 301 and 312 respectively, of each of the annular belts 41 functions as an inlet and an outlet of the clamping and conveying passage for the valuable 15 document, an opening 13 is provided in the casing 1 at a position corresponding to the inlet of the clamping and conveying passage, and symmetrically, an opening 14 is provided in another side of the casing. Each of the transparent rotating cylinders is provided with two information collecting devices 51. Referring to Figures 3 to 5, the connection relationship between the information collecting devices 51, the transparent rotating cylinders 21 and the casing 1 is 20 further illustrated. Each of the two transparent rotating cylinders 21 is rotatably connected to side walls 11, 12 via a hollow bearing 211 and obtains power from a driving motor 6 via a gear 2111, and information collecting elements of the information collecting devices 51 are fixedly connected to a connecting member 7. The connecting member 7 passes through the hollow bearing 211 of a glass rotating cylinders 21 without contacting with the hollow bearing 25 211 and is fixedly connected to side walls 11, 12, wherein a collecting end of each of the information collecting elements faces a portion of the outer surface of the annular clamping belt. [0040] Further, the annular clamping belt 41 is driven by the driving motor via the tension wheel 301 or 302 to move synchronously with the transparent rotating cylinder in a direction 30 opposite to the rotation direction of the transparent rotating cylinder. [0041] In order that the valuable document may smoothly enter into the clamping and conveying passage, a driven wheel 3011 is provided at an inlet end of the clamping and -6- English translation of PCT/CN20 12/083555 conveying passage at a position corresponding to the tension roller 301, and the inlet and the outlet of the clamping and conveying passage are both provided with a guiding sheet 8. Referring to Figures 6 and 7, the guiding sheet 8 is provided coaxially with the driven wheel 3011, and a guiding end 81 of the guiding sheet 8 is in contact with the outer surface of the 5 transparent rotating cylinder 21 via a torsion spring 82, thereby realizing a guiding effect during the entering and leaving of the valuable document. [0042] In order to obtain a depth information and a magnetism information of the valuable document simultaneously, a depth collecting device 91 and a magnetic signal collecting device 92 are provided on conveying paths through which the valuable document enters and 10 leaves the clamping and conveying passage in this embodiment. Further, in order to effectively control the operation of the collecting device of the valuable document identification device, trigger sensors 93, 94 are provided respectively at the inlet and the outlet of the valuable document. When the trigger sensor 93 detects the entering of the valuable document, the valuable document identification device is started; and when the 15 trigger sensor 94 detects the leaving of the valuable document, the valuable document identification device is stopped. [00431 Further, referring to Figure 8, in order to ensure the collection of valid data of the valuable document by the information collecting device 51, an installation position relationship between the information collecting element of the information collecting device 20 and the transparent rotating cylinder 21 is required to meet the following condition: [0044] FOV = OXWN r x Ha [0045] Wherein, "FOV" is a field angle of the information collecting element, "WN" is a width of the valuable document collected within the field angle, "Ha" is a distance between the valuable document and an apex of the field angle, and "WN" is equal to the minimum 25 note-like medium width "WNmin" collected by the collecting device and calculated according to the requirement of image collection resolution. [0046] In order to further illustrate working principle of the valuable document identification device, an identification process of the valuable document by the device is illustrated in conjunction with Figures 2 to 10. For simplifying the illustration, herein the 30 valuable document is set to enter into the valuable document identification device via the opening 13 and leave the valuable document identification device via the opening 14. And in -7- English translation of PCT/CN2012/083555 practical use, the valuable document identification device has a bidirectional use function. [0047] When the valuable document is conveyed to the opening 13, the trigger sensor 93 detects the valuable document, then the valuable document identification device is started. The transparent rotating cylinder 21 and the annular clamping belt 41 are respectively driven 5 by respective driving motors to move, and linear velocities of the movements of the outer surface of the annular clamping belt 41 and that of the outer surface of the transparent rotating cylinder 21 are consistent. After passing through the magnetic signal device 92 mounted at the opening 12, the valuable document is guided by guiding sheet 8 to enter into a movement clamping passage formed between the outer surface of the annular clamping belt 41 and the 10 outer surface of the transparent rotating cylinder 21 and is clamped to move forward along with the movements of the outer surface of the annular clamping belt 41 and the outer surface of the transparent rotating cylinder 21. When the valuable document is moving forward, the image of the valuable document is collected line by line by the information collecting device 51 which collects the image of the valuable document. 15 [0048] In this solution, two sets of the transparent rotating cylinder 21, the annular clamping belt 41 and information collecting devices 51 symmetrically arranged are employed, thus after the valuable document passes through one clamping and conveying passage, two additional guiding sheets 8 has to be provided to guide the valuable document to smoothly enter another clamping and conveying passage from one clamping and conveying passage. 20 When the valuable document is moving forward in said another clamping and conveying passage, the image of the other side of the valuable document is collected, then the valuable document is conveyed out via the outlet 14. When being conveyed out via the outlet 14, the depth information of the valuable document is obtained by the depth sensor 91 arranged at the outlet 14, and when the trigger sensor 94 detects that the valuable document has left, the 25 valuable document identification device is stopped. [0049] Further, it is to be noted that, the control of the working state of each collecting device may be started and stopped one by one depending on the coming of the valuable document, specifically the conveying speed of the valuable document being clamped is calculated according to the triggering of the trigger sensor 93 to calculate the time period that 30 the valuable document passes through each collecting device, so as to control the collecting time of each collecting device. -8 - English translation of PCT/CN2012/083555 [0050] The above descried embodiments are only the preferred embodiments of the present application. It is to be noted that, the protection scope of the present application is not limited to the above preferred embodiments, and is defined by the claims. For the person skilled in the art, many modifications and improvements may be made to the present application 5 without departing from the spirit and scope of the present application, and these modifications and improvements are also deemed to fall into the protection scope of the present application. .9.
